GEORGE H. F. SOHRADER, OF NEW YORK, N. Y.

WATER-BOTTLE STOPPER.

SPECIFICATION forming part of Letters Patent No. 504,138, dated August 29, 1893.

Application filed July 9, 1892. Serial No. 439,511. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. F. SCHR/ADER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Water-Bottle Stoppers, of which the following is a specification.

This invention relates to stoppers for water bottles or bags, and to analogous closures and particularly to valved stoppers, such as are used for fountain syringe bags. I

The object of my invention is to provide an improved valved stopper which shall be of cheap and simple construction, and convenient and effective in operation.

Heretofore various constructions of valved stoppers have been employed, among which may be cited that shown in my UnitedStates Letters Patent No. 476,421, dated June 7,1892, in which the stopper proper of the water bag was traversed by a tubular screw threaded stem having at one end a valve and at the other end a nozzle for receiving the tube of a syringe, the stopper operating when the valve is closed as an ordinary water bag stopper, and when the valve was open as an outlet through which the contents of the bagmight flow to the syringe.

In carrying out my present invention I provide certain improvements in the construction and arrangement of the stopper and its valve and nozzle and handle, all of which will be fully hereinafter set forth.

In the accompanying drawings, which illustrate one adaptation of my invention, Figure 1 is a side elevation of my improved stopper constructed according to the preferred form of my invention, the thimble and neck of Let 0 indicate the stopper as a whole, D its nozzle, and E its valve.

The vessel A and socket B may be of any well. known construction. In the construction shown the socket is a tubular thimble about which the neck of the vessel A is molded, which is constructed with an internal screw thread a and at bottom with an annular valve seat I).

The stopper 0 may be of any known construction. That shown is myimproved stopper consisting of a hollow inverted cup 0, to which the nozzle D is secured at top, which is closed at bottom by some suitable provision, as for example the lower disk or piece D. The stopper has an external screw thread (1 adapted to engage the screw thread a of the thimble whereby by rotating the stopper it can be adjusted toward and from the seat b. At bottom it carries the packing washer F for engagement with the seat. At top it may have any well known handle, but I prefer to construct it with my improved handle G, which consists of a short bar or rod fixed within the nozzle D by passing it through holes 6 e in an enlarged portion f of the nozzle and then soldering it in position as best seen in Fig. 2, whereby the handle traverses the conduit through the nozzle and the latter serves to support it and connect it to the body of the stopper.

Preferably the nozzle D consists of a separate tubular piece riveted or otherwise socured in an aperture g in the head of the stopper. It is shown in Fig. 2 as constructed with a reduced lower end fitting this aperture having a shoulder abutting against the top surface of the stopper and having its lower end swaged against the inside thereof. At its other end it is preferably constructed with a small head or lip for engagement with the syringe tube.

According to my invention the valve E is preferably constructed as a tubular stem 71. traversing the inner end or wall of the stopper, screw threaded externally at c to engage corresponding screw threads j in the wall of the stopper, having an inlet aperture without the stopper, whereby a continuous conduit exists through the wall of the stopper whenthe valve is open, and having a head Z exteriorly of the stopper by means of which it can be rotated to adjust it on its screw threaded connection with the stopper to open or close it. Preferably the head Z is knurled. Preferably the valve is fixed to the stopper with its inner end within the hollow body thereof, whereby this end is concealed, and preferably it is made irremovable from the stopper, by some provision such for example as swaging its inner end at m to overlap the adjacent surface of the stopper. Preferably I construct the lower edge of the stopper 0 with a rabbet ninto" which the disk 1) fits, and which is swaged against the disk to make the necessary joint to connect the parts together. Preferably the washer]? is carried by the stopper, and con nected thereto by aheaded stud 0 over which itis sprung. Preferably thisstuclis athimble united to the disk-D by havingits reduced-neck passed through the perforation pin the di k d rivetedtherein, and the screw thread j is formed on the inner side of thisithimble. Preferably the outer face of the thimble constitutes the seat for the valve E, and the lat ter is provided with a packing ring H sprung i to a groove qabove itshead for insuring a tight joint whenthe valve is closed.

Inassembling the stopper when constructed as "shown the cup 0 and nozzle D are first rivetedtogether; the thimble 0 is riveted to the diskD' the valve stem his screwed into the thimble and its endsswaged outwardlyythe disk is then united to the cup, whereupon the packing washers may be sprung into their respective positions or they may be located bef re-connecting the parts together as-desired.

In operating my improved stopper th'e valve E is ordinarilyscrewed to the closed position, audits seat being of less diameter thanthe internal diameter of the seat bpass within the latter as the stopper is screwed into the socket B until'its washer-F mak with the seat I) for closing the v l A; When it is desired to use the bag for a fountainsyringe the stopper is removed, the valv screwed to the open POSitlOIl, the stopper relaced,and the syringe tube passed over the end ofthe nozzle D, whereupon on inverting the bagA its contents can flow through the aperture and through the hollow lnterlor of the stopper, and through its nozzle F to thesyringe tube. v t

It willbe understood that my invention 15 not limited to the particular details of conand stem h of the valve E into features and combinations, substantially as hereinbefore set forth, namely:

1. In a stopper for water bottles, the combination with a hollow body having an aperture at its upper end and a screwthreaded aperture at its lower end, of a nozzle carried by the upper end=of said body and in communication through the upper aperture thereof with the interior of said body, and a valve, consisting of an externally screwthreaded tubular stem provided with a port in the body thereofand having a head onits lower end, whereby it is adapted to enter the lower screw-threadedaperture of the hollow body, be concealed therein, exteriorly close said aperture andthereby control communication through said body, substantially as set forth.

2. A screw stopper consistingof twoparts, the one constituting. the outer endrof the stopper and havinga 'nozzle, and the other "united thereto, constituting (the inner! end of the body, and carrying a'valvemonstructed when in oneposition to permit communication through the body to the nozzle, and when iinzthe'other position to close such communication.

. 3. i In a'screw stopper, a body having. an internal conduit fromlits innervend.tolitsouter end; and consistingiof two; parts'nnited together, the one 'partiformingthe outer end of the bodyvandthe otherv part formingthe inner endfit'hereof, in'combination with a tubullar thimble'aso, carried bylthewlatterrofsaid .parts, and communicating with. the conduit .inl said -body, a packing washerz' as F carried .by said thimble at the innerlendofl said 'body, and a valve as E, traversing.said thimble,and adjustable therein for closing communication therethrough, substantially. as and: for the'p'urpose set forth.

4. i In a screw stopper abody consisting of the cup 0 constituting the outer spartith'ereof, the disk D united to said cup to close its bottom and constituting the inneraend of the body,atubularthimble o rivetedito said disk and communicating with the interior: ofi the body, a washer F carried by. said thimble at the inner end: of thebody,and1avalve E having a'stem h traversing saidtubular thimble and swaged outwardly within: said cup, and having'the head lat" its outer end exteriorly of the inner end of said body, substantiallyasand for the purpose set forth.
